cloudflare_dynip

A lightweight Golang program to update Cloudflare's DNS record when using a dynamic IP address. It is designed to be run in a Docker container and is lightweight (13Mb docker image).

Installation

The first step is to get an API token from Cloudflare:

1. Go to My Profile/API Tokens
2. Click Create Token
3. Use the Edit zone DNS template
4. In the Zone Resources category, select the domain you want to use
5. Copy the generated token for later

You can now run cloudflare_dynip using the docker run:

docker run -d -e DOMAIN=example.com -e API_TOKEN=yourkey alexandresnr/cloudflare_dynip:latest

The check will be run every 5 minutes by default but can be changed by modifing the CRON_STRING env variable (example: @every 5m).
